Which is all fine and dandy.. you still haven't addressed my original question. Why can I find (1000's arguably) excellent open source variants to "commercial" software... but maybe 10, if I'm lucky, proper and decent Open Sourced 3D games? There's the difference. Difficulty be damned ( I don't want to get into a pissing match between cultures here.. personal bias and/or emotions are not the way to discuss something ) - what matters is what the end user can get. I can get OSS that will replace my commercial needs... I can't get OSS software to replace my gaming needs.
